Abstract

Prodn. of hydroxyethylthio-benzaldehydes and their oxidn. prods. of formula (I) is effected by (a) reacting 1 mole of a halobenzaldehyde of formula (II) with 1-1.5 mole (per halogen atom to be substd.) of 2-mercaptoethanol (III) in an aq. medium contg. an acid binder at 70-150 deg.C, and (b) oxidising the prod. with H2O2 in the presence of a hexavalent W catalyst at 40-110 deg.C, where R = H, F, Cl, Br or i; m = 0 or 2; n = 1 or 2; p = 0 or 1, provided that p = 0 when m = 0; X, Y and Z = H, F, Cl, Br or I, provided that 1-3 of R, X, Y and Z are halogen and that R is halogen when 3 of R, X, Y and Z are halogen.
